NEUROHEMAL ORGAN Meaning and
Definition
-
A neurohemal organ is a specialized structure found in some organisms that functions as a storage and release site for neurosecretory substances. It is typically composed of neurons and blood vessels that are closely associated, allowing for the release of neurohormones or other chemical signals directly into the bloodstream. This unique arrangement allows for efficient communication between the nervous and endocrine systems.
Neurohemal organs are typically distributed throughout the body and can be found in various organisms including invertebrates such as insects and mollusks, as well as vertebrates like mammals and birds. These organs play a crucial role in regulating diverse physiological processes including growth, reproduction, metabolism, and behavior.
The neurons within a neurohemal organ produce neurohormones or neuropeptides that are transported along their axons and then stored within the organ until they are stimulated to be released. Upon stimulation, these neurosecretory substances are released into the bloodstream, where they can act on target tissues or organs located throughout the body, exerting their effects.
Neurohemal organs provide a means for rapid, long-distance communication within the body, allowing for precise regulation of various physiological processes. They are critical in coordinating diverse functions of an organism and maintaining homeostasis. Through their involvement in endocrine signaling, neurohemal organs play a fundamental role in the integration of neural and hormonal communication systems, thereby contributing to the overall physiological and behavioral responses of an organism.

Etymology of NEUROHEMAL ORGAN
The word "neurohemal organ" is composed of two main parts: "neuro" and "hemal".
The term "neuro" is derived from the Greek word "neuron", meaning "nerve". It refers to anything related to nerves or the nervous system.
The term "hemal" is derived from the Greek word "haima", meaning "blood". It pertains to anything related to blood or the circulatory system.
The word "organ" comes from the Latin word "organum", meaning "instrument" or "tool". It refers to a group of tissues working together for a specific function.
Therefore, the etymology of "neurohemal organ" reflects its meaning as an instrumental structure related to nerves and blood. In biology, a neurohemal organ is an organ that stores or releases hormones or neuropeptides into the bloodstream under the control of nerve fibers.
